This is really cool. I have noticed that I get the best mileage in stop and go as well. As long as i dont have to stop and lose momentum. I usually just cruise in the right hand lane. I am to scared to try your new theory as every time I give my jeep gas I feel like I am burning money away. My method is to use as little throttle as possible and inflate my tires to max PSI. Also, I don't think this method would work well, because my jeep is an auto so it will down shift upon a heavy foot. Is it worth a try or no? Oh side note I cleaned my injectors, replaced my fluids, and changed my spark plugs so maybe I can hit 18 this week.
